Abstract: Certain aspects of the present disclosure relate to methods and apparatus for updating beam information across a plurality of component carriers (CCs) via downlink control information (DCI). An exemplary method, performed by a user equipment (UE), generally includes receiving, from a network entity, a downlink control information (DCI) for an update for at least of a beam or path loss (PL) reference signal (RS) activation and applying the update across at least one of a group of component carriers (CCs) or bandwidth parts (BWPs) within the group of CCs.

Abstract: Techniques for dynamic configuration of channel state information (CSI) processing units are disclosed. In an example, a user equipment (UE) may determine an operational state of the UE. The UE may also identify a number of channel state information (CSI) processing units that are supported by the UE for calculating and reporting one or more CSI reports based on the operational state of the UE. The UE may also transmit, to a base station, a notification indicating the number of CSI processing units.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a control resource set (CORESET) is not configured for an active downlink bandwidth part of a component carrier (CC) of the UE. The UE may determine that a transmission configuration indication (TCI) state is not activated for a physical downlink shared channel (PDSCH) of the active downlink bandwidth part of the CC. The UE may determine a default spatial relation for an uplink control channel or uplink signal for the CC based at least in part on determining that the CORESET is not configured for the active downlink bandwidth part of the CC and that the TCI state is not activated for the PDSCH of the active downlink bandwidth part of the CC. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes performing beam failure detection (BFD) of a beam pair link (BPL) associated with a secondary cell (Scell) of a base station (BS), sending a beam failure recovery request (BFRQ) message in another cell of the BS, the BFRQ message including an indication of a candidate recovery beam for the Scell, and starting a timer based on sending the BFRQ.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a set of beam failure detection reference signals to monitor for a set of secondary cells based at least in part on at least one of a cell configuration, a set of secondary cell reference signal selection rules, or a set of primary cell reference signal selection rules; monitor the set of beam failure detection reference signals based at least in part on determining the set of beam failure detection reference signals; and detect, based at least in part on monitoring the set of beam failure detection reference signals, a beam failure for a secondary cell of the set of secondary cells. Numerous other aspects are provided.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for receiving, by a network entity from a user equipment (UE), a component carrier/bandwidth portion (CC/BWP) grouping capability message that indicates a capability of the UE to support CC/BWP group-based signaling; transmitting, by the network entity to the UE, a CC/BWP grouping indication that identifies at least one CC/BWP group based on the CC/BWP grouping capability message; transmitting, by the network entity to the UE, a CC/BWP configuration message that includes CC/BWP group configuration information that identifies a CC/BWP group configuration for the at least one CC/BWP group; communicating, by the network entity with the UE, on at least one CC/BWP of the at least one CC/BWP group based on one or more communication parameters configured according to the CC/BWP group configuration.

Abstract: Apparatus, methods, and computer-readable media for facilitating spatial relation indication for uplink control channels and SRS are disclosed herein. An example method for wireless communication at a UE includes determining, based on a rule, a default uplink transmit beam for transmitting an uplink transmission when an uplink transmit beam is not configured by a base station for the uplink transmission. The example method also includes transmitting, to the base station, the uplink transmission on the default uplink transmit beam.

Abstract: Control for multi-panel user equipment (MPUE) activation may be performed by both the MPUE and a base station. The MPUE may have at least a first panel and a second panel. The MPUE may send to the base station, a request to change an activation status of at least one panel of the MPUE. The base station may transmit a response indicating whether the request has been approved. The MPUE may change the activation status of the panel according to the response. Conversely, the MPUE may receive a command from the base station to change an activation status of at least one panel of the MPUE. The MPUE may determine whether to follow the command or override the command. The MPUE may transmit a response indicating whether the MPUEUE has followed the command or overridden the command.

Abstract: A UE detects a beam failure on a first CC. The UE determines whether to transmit a BFRQ to a base station on the first CC or a second CC. The UE determines whether to include a NBI report in the BFRQ. The UE transmits the BFRQ to the base station on the first CC or the second CC. The base station receives a BFRQ from a UE on a first CC or a second CC. The base station determines a new beam for the first CC, where the determination of the new beam is based on a RACH procedure when the BFRQ is received on the first CC or a NBI report in the BFRQ when the BFRQ is received on the second CC. The base station initiates a BFR procedure with the UE for the first CC based on the BFRQ and the new beam determination.
